IMPRJOVEI-MENT IN STATI ON INDICATO RS.

Specification forming part of Letters Patent No. 197,728, dated December4, 1877 application filed I I November 6, 1877.

To all whom it may concern:

Be it known that I, GEORGE M. GUILD, of Boston, of the county of Suffolkand State of Massachusetts, have invented a new and useful Improvementin Stationlndicators for Railway-Carriages; and do hereby declare thesame to be described in the following specification and represented inthe accompanying drawings, of which- Figure l is an elevation of myinvention as applied to a car. Fig. 2 is a longitudinal section, andFig, 3 a transverse section, of the car.

In such drawings, A denotes a case arranged within the car B, and havingwithin it an endless belt, 0, on whose outer surface the names of theplaces or stations are to be printed or affixed in any suitable manner,and they are to be brought successively in rear of an opening, a, so asto be seen by passengers in the car.

I contemplate using one of my station-indicators at each endof the car.The endless band goes around two supporting-drums, D E, arranged asshown, there being on the shaft a of the lower one a gear, F, toco-operate with two pawls, G H, disposed over it. They are pivoted totwo levers, I K, arranged, as shown, on one fulcrum, b. The upper armsof these levers, by means of linesc o, extending from them, asrepresented, are connected with a slide-bar, L, arranged on the top orother suitable part of the car. Furthermore, there is fastened to eachpawl one of two-lines, d d, that extend up from it, in manner as shown,and go through eyes or guides e e, and are fastened to the slide-bar.Each lever has fixed to it and the car a spring, f, to retract it, bymeans of a line, f, extending from the lever to a bell, g, and thence upto a stationary eye, h. One of the levers has applied to it a bell forgiving notice of a movement of the endless band.

0n moving the slide-bar in either direction lengthwise of it, one pawlwill be raised out of action with the gear, and the other will be forcedinto engagement With such gear, and will partially revolve it, so as tomove the belt in a manner to bring into view the name of a station, orthat to which the car may be appreaching.

The endless belt may have a series of re-- the belt, and such means ofconnecting the two, 0 being the belt, k the plate, I l the staples, andm the spring.

The opening a of the casing I provide with a door, n, hinged to it. Thisdoor, by means of a line, 0, I connect with the wrist of a crank, 12,projecting from a shaft, q, that goes up through the roof of the car,and is provided with a wing or vane, it, all being essentially asrepresented. As the car may be moved forward, this vane will be turnedby the wind or atmosphere, and will'raise the door, so as to enablepersons in the car to see the indicator.

The door of the indicator at the opposite end.

of the car will be closed by its vane. Thus it will be seen that, whenthe car is moving one Way, the door will be closed but when moving theopposite Way, the door will be opened. This is to prevent a passengermistaking a station by reading from the indicator at the rear end of thecar.

Immediately after the car may have left a station, the conductor orother officer of the train is to move a slide-bar, so as to cause thename of the next station ahead to appear at the opening a. Should heaccidentally omit to do this, there is combined with the indicator amechanism for automatically effecting such. It consists of a wheel, P,fixed on the shaft of the lower drum of the endless band C.

This Wheel has a series of teeth or arms, S, projecting radially fromits circumference.

At some proper part of the road-bed there should be one or more postsset up for the lowermost of the arms S to be carried in contact withwhile the carriage may be passing such post or posts, the whole beingso' that the wheel may be made to revolve the required distance forcausing the name of the approaching station to appear at the opening a.

I claim as my invention as follows:

1. The combination, substantially as -described, for operating thestation-indicator endless belt 0, as set forth, such consisting of thegear F, pawls G H, leversIK, springs f anism for actuating thestationindicator endless belt.

3.The combination of the vane t, shaft q, crank p, and the line 0 withthe car and the door or of the opening a of the case of thestation-indicator,all being arranged to operate as explained.

4. The combination for securing each nameplate to the endless belt, suchconsisting in the notehes in the plateand-the staples and spring appliedto the belt, all being arranged as represented. a a
